Interface names must start with `tun` or `tap` on BSD and Darwin

The tun interfaces on my Mac are all named "utun0", "utun1", etc.
How can I make scapy work with that?

That’s indeed a bug.

@guedou I looked at the code today. Unfortunately it's not just a naming issue; the socket type and ioctl are different. I'll give it a try later this summer. Any suggestions are welcome :)

Hi @guedou,

Sorry about the radio silence.
I got it to work a month ago, but then had a bunch of stuff come up, so I forgot about it.

I opened a draft pull request with the changes that I made.

There is still a lot of work to be done before it can be merged (adding tests, refactoring, etc.).
Unfortunately, I have zero time at the moment; I hope that someone can take it over 🙏
